UNITED OFFICE ALFRED THAUSS, OF COLOGNE-DEUTZ, AND GUSTAV MAU'THE, OF COLOGNE-HOLWEEDE, GERMANY, ASSIGNORS TO GENERAL ANILINE WORKS, INC., OF NEW YORK, N. Y., A COBIPORATION OF DELAWARE WATER-SOLUBLE PRODUCT DERIVED FROM: THE FATTY ACIDS OCCURRING IN WOOL EAT AND PROCESS OF PREPARING THE SAME Ho Drawing. Application filed December 16, 1927, Serial No. 240,625, and in Germany December 17, 1926.
